What Is a Viettel eSIM?
A Viettel eSIM is a virtual SIM card embedded into your smartphone. It allows travelers to enjoy data and calling services without the need for a physical SIM. Viettel, Vietnam’s largest network provider, offers wide coverage and reliable internet speeds across the country.
Benefits of Viettel eSIM for Tourists
- Instant Activation: Receive a QR code via email within 10 minutes of purchase.
- No Physical Handling: No need to remove your home SIM or carry multiple SIM cards.
- Wide Coverage: Viettel covers both cities and remote areas such as Sapa, Ha Giang, or the Mekong Delta.
- Affordable Plans: Flexible data plans from just $6.90 with no rental fees.
- Phone Number Included: Most eSIMs come with a Vietnamese phone number for Grab, banking OTPs, and local calls.
What Is a Pocket WiFi?
A Pocket WiFi is a small portable device that creates a personal Wi-Fi hotspot. You connect your phone, laptop, or tablet to this hotspot for internet access. Many travelers rent Pocket WiFi at the airport or online before arrival in Vietnam.
Benefits of Pocket WiFi
- Supports Multiple Devices: Connect up to 5-10 devices at once — ideal for families or group travel.
- Familiar Usage: Easy setup similar to using a home Wi-Fi router.

In the next section, we’ll explore Pocket WiFi rental logistics, hidden costs, real-world performance, and help you decide which option suits your travel style best.
Real-World Performance: Viettel eSIM vs Pocket WiFi
In real-world scenarios, the Viettel eSIM consistently outperforms Pocket WiFi in terms of reliability and speed. Since eSIMs connect directly to Vietnam’s largest mobile network (Viettel), users experience stronger signals even in mountainous areas like Sapa, or off-grid destinations like Ha Giang or Con Dao.
Meanwhile, Pocket WiFi may lose signal in rural or forested areas because it often relies on smaller network partnerships and may have throttled bandwidth when multiple devices are connected. Battery life and overheating also affect stability.
Speed Test Comparison
- Viettel eSIM: Download speed up to 90 Mbps in major cities.
- Pocket WiFi: Download speed typically 30–50 Mbps, can drop below 10 Mbps with 3+ devices connected.
Hidden Costs of Pocket WiFi
Many tourists are initially drawn to Pocket WiFi rental because of perceived ease, but soon encounter hidden costs:
- Deposit fees (often $50–$100, refundable but risky if lost).
- Late return penalties (up to $10/day).
- International shipping fees (if renting before arrival).
- Power bank rental or additional cable rental charges.
On the other hand, a Viettel eSIM from GoVnSIM requires no shipping, no return, and has transparent one-time pricing.
Security & Privacy Comparison
Another factor many travelers overlook is security. With a Pocket WiFi, your data passes through a third-party device that may not be secured. If you lose it or connect to public Wi-Fi, your sensitive data could be at risk.
Viettel eSIM, being embedded directly in your phone, avoids these risks. Your mobile data connection is encrypted via the network, just like a regular SIM.
What Do Travelers Say?
Here are real-life examples of traveler experiences:
“I used Viettel eSIM from GoVnSIM on my trip to Da Nang and Hoi An. Setup was instant. No hassle, no device to carry. Just perfect for solo backpackers like me.” — Jasmine, UK
“We rented a Pocket WiFi for our family trip, but it kept disconnecting. Kids got frustrated, and we had to carry it and keep recharging. Next time, I’ll try eSIM for everyone.” — Leo, Singapore
Who Should Choose Pocket WiFi?
Despite its downsides, Pocket WiFi may be suitable in some cases:
- Traveling as a group or family of 3–5 people.
- Using tablets or laptops that can’t install eSIMs.
- Staying in cities only, not remote areas.
Who Should Choose Viettel eSIM?
Viettel eSIM is ideal for:
- Solo travelers or couples who value minimalism and speed.
- Remote work professionals, digital nomads.
- Those who want instant connectivity upon landing.
- Long-stay travelers who need a local phone number (for Grab, OTP, Zalo).
Final Verdict: Viettel eSIM or Pocket WiFi?
If you value convenience, instant setup, nationwide coverage, and secure access, Viettel eSIM is the superior option for most tourists. Pocket WiFi only makes sense for large groups who need shared connectivity and don’t mind carrying extra gear.
